This is like asking is there an ideal amount of crime? The bigger question is what kind of society do you want to build? If you want a stable society you will work towards ensuring people have decent income, possibilities to grow and overall wider distribution of income. The alternative is oppression when people react to their conditions. There is no point having a few people capturing the wealth of and productivity of a society. Yet you are already born into a society with rent seekers and individuals who hold a huge amount of wealth. The top 1% already control the economy and assets. Discussion about inequality then is moot as it only perpetuates an illusion of control and freedom to decide the issue when there is none.
